The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an ...
An ECG may show signs of right heart strain or acute cor pulmonale in cases of large PEs – the classic signs are a large S wave in lead I, a large Q wave in lead III, and an inverted T wave in lead III (S1Q3T3), which occurs in 12–50% of people with the diagnosis, yet also occurs in 12% without the diagnosis.
Right-sided heart failure is often caused by pulmonary heart disease (cor pulmonale), which is typically caused by issues with pulmonary circulation such as pulmonary hypertension or pulmonic stenosis. Physical examination may reveal pitting peripheral edema, ascites, liver enlargement, and spleen enlargement.
To rule out an enlarged spleen, a pretest probability of 30% or less will yield a negative predictive value over 90% (calculation) Given the paucity of physical exam findings to evaluate possible splenomegaly, Castell's sign is the most sensitive, and is thus a good tool to teach in an advanced-type physical diagnosis course.
Cor pulmonale PAH is considered a universally fatal illness, although survival time may vary between individuals. The prognosis of pulmonary arterial hypertension (WHO Group I) has an untreated median survival of 2–3 years from time of diagnosis, with the cause of death usually being right ventricular failure ( cor pulmonale ).

Right Atrial Enlargement (RAE) increases the p wave, representing atrial depolarization, on an ECG to an amplitude > 2.5mm in lead II, an abnormality referred to as p-pulmonale, likely due to weakened right atrial myocardium close to the Sinoatrial (SA) node.
Kehr's sign is the occurrence of acute pain in the tip of the shoulder due to the presence of blood or other irritants in the peritoneal cavity when a person is lying down and the legs are elevated. Kehr's sign in the left shoulder is considered a classic symptom of a ruptured spleen.
When this leads to right sided heart failure, it is known as cor pulmonale. [4] Symptoms of this disorder occur because the heart has difficulty pumping blood from the body through the lungs. Fluid may, therefore, accumulate in the skin of the legs in the form of edema (swelling), and in the abdominal cavity in the form of ascites ; decreased ...
